Thermal Stability Of

Spectroscopic properties and energy transfer (ET) in Er3+/Eu3+-doped Ga2O3-GeO2 glass have been investigated. Effects of alkali metal and alkaline earth metals ions on thermal stability of Er3+-doped gallate-germanium glass have been investigated. Simultaneously influences of Eu3+ codoping on the optical properties of Er3+-doped Ga2O3-GeO2-Na2O (GN) glass have been investigated and the possible ET mechanisms involved have also been discussed. Significant enhancement of the 1.53 µm emission intensity and decrease of upconversion (UC) fluorescence with increasing Eu3+ concentration have been observed. The results indicate that the incorporation of Eu3+ into Er3+-doped GN glass can effectively improve 1.53-μm and lower UC luminescence, which makes GN glass more attractive for their use in C-band optical fiber amplifiers.
